Ads pay miniscule amounts per view… I’ve heard it said the £12/month sub is about hundreds of times what they get from ad revenue per user. So they spam them everywhere… the more ads the better.
Which means people block the ads because they’re obnoxious, and they make nothing…
Happens with americans too… they seem to completely miss sarcasm sometimes. Humour is very cultural (and often plays into things a native of the country would know but someone outside sometimes wouldn’t).
